• Chemical control (1) Rogor-40 at 1 fluid oz. in
  4 gallons of water and (2) Lebaycid at 1 1/2
  fluid oz. in 4 gallons of water.

  fall to the ground.Control    malathion 50 per
  cent emulsion or fenitrothion (available as
  verthion, agrothion, or folithion-all at 50 per
  cent emulsion) at 1 1/2 fluid oz. in 4 gallons of
